It works.

October 27, 2014
After a total engine rebuild, the flathead engine in my 1940 Ford leaked from every pore. Before installing the Moroso product, I removed the cylinder heads and applied a thread sealer (procured locally) to the stud threads in the engine block. After starting the engine again, the leaks continued for a few minutes but gradually stopped. Needless to say, I was very pleased.
Yes, I recommend this product.

Will this product not work if I use anti-freeze in the block? Will be used on a Ford flathead. Thanks, Bill

This engine sealer does not work with anti-freeze. We do offer part #9104120 if using for cooling system
